Abstract

Matrix (or operator) recovery from linear measurements is a well studied problem. However, there are situations where only bi-linear or quadratic measurements are available. A bi-linear or quadratic problem can be easily transformed to a linear one, but it raises questions when the linearized problem is solvable and what is the cost of linearization. 
In this work, we study a few
